!
Caution
According to the regulation for pressure reser-
voirs all pressure reservoirs must be repeated-
ly inspected by a specialist. In this sense
repeated inspections are external examina-
tions, normally on pressure reservoirs in oper-
ation. In connection with this inspection the
drier/collector unit must be visually examined
twice every year. During these inspections
special attention must be paid to corrosion
and mechanical damage. If the reservoir is not
in proper condition it must be replaced for
safety reasons, as a precaution to protect op-
erators and third parties against any danger
arising from the handling and operation of
pressure reservoirs.
!
Danger
Danger of injury!
In case of mechanical damage or corrosion on
this drier/collector unit this unit must be re-
placed, to avoid bursting and further damage.
